Problem IC79105 | Status: Geschlossen |
CLIENT MIGHT SEGV (CRASH) IN SQLEUCFREEDIAGINFO() DUE TO DEREFERENCING AN ALREADY FREED MEMORY | |
Produkt: | |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 | |
Problembeschreibung: | |
Client process, like dsmserv, can SEGV (crash) with the following stack trace: sqleUCfreeDiagInfo() sqleuResetUCintfc() [sqleUCinitUCintfc()] sqleUCappConnect() sqleStartUsingDatabase() sqlubConnectDatabase() db2Backup() DB2BackupThread() StartThread() The function in '[]' will or not show up depending on the compiler that was used. The crash would happen in sqleUCfreeDiagInfo() because we are trying to dereference memory that is pointing to freed (and possibly reused) memory. This might happen if a previous connection attempt would have failed. | |
